Imported GPX routing

[Michael Tanner]

Hello,

I just joined this OSMand group.  I found it a few days ago by experimenting with using a Raspberry Pi 4 with android installed on it.  It works but I just need purchase and attach a GPS antenna.  The reason for me doing this is to use it as a navigation system while snowmobiling.  All of this after getting a Garmin GPS working just a few months ago.  I'm always looking for new ways.

Anyways, in OSMand with a GPX file converted  (gpsbabel) from a google maps KMZ file .  Actually the KMZ file is unzipped and I use the KML file.  There are 2 KML files in the KMZ.  So far I can't see any difference in the data so I just convert one of them.

I have yet to actually try this on the snowmobile.  But I have been trying different places that we snowmobile to/from both in searching and simulated tracking.  I have tried the auto profile but it routes along roads and not the GPX snowmobile tracks.  Next, I created a snowmobile profile using bike as a base.  This actually seems to work in that it routes along most of the GPX track but there are still some off GPX roads/paths that it uses. 

I then choose the option "follow track" to try and force it to route on just the GPX snowmobile tracks.  However, most of the time it crashes.  I believe it is routing along the entire 22,958 miles of tracks in this GPX file.  One time it didn't crash and showed me going something like 30,000 miles in 400 hours give or take LOL.

I then realized that it is using the ENTIRE GPX track of 22,958 miles. 

I am new to this and I did get this same snowmobile map working on my garmin.  My state DNR provides a free garmin IMG with this data.  I had to install a topo IMG file and disabled the garmin base map.  It then routes along the snowmobile trails.  The same state DNR has the google KMZ as well which is where I have been trying on my android phone and the raspberry pi.

I've looked at the GPX file and this is what I see...

Then the next track in that clubs system.  So, what am I missing?  It seems like it is one continuous track of 22,958 miles.  Can anyone help in why i have to use bike to get it to half route along these snowmobile trails? How to force it on snowmobile track?

I can post a link to this KMZ if anyone wants to try it.  It is freely available for use.

Thank you,
